A. Kilonda et al., SYNTHESIS OF 6-AZIDO AND 6-AMINO ANALOGS OF 1-DEOXYNOJIRIMYCIN, Journal of the Chemical Society, Chemical Communications, (18), 1994, pp. 2147-2148
Selective isopropylidenation of the 2,3- and 5,6-hydroxy groups of 1-[
(tert-butoxycarbonyl)amino]-1-deoxy-D-glucitol 5b led to the diacetoni
de 6 which was converted in seven steps to the selectively protected 6
-azido compound 3, a valuable precursor of various derivatives of 6-am
ino-1,6-dideoxynojirimycin 4b.
